TI-IRUST-BEARING.

Specification of Letters Patent.

Patented Mar. 21, 1911.

To all whom it may concern:

Be it known that I, THOMAS S. PATTERSON, a subject of the King of Great Britain and Ireland, residing in Rosemont, Pennsylvania, have invented certain Improvements in Thrust-Bearings, of which the following is a specification.

My invention relates to certain improvements in bearings especially designed for use in centrifugal separators or washers driven by a turbine motor, and one object of my invention is to provide improved means for supporting the basket of the device without employing a step hearing.

In the accompanying drawings :Fignre 1, is a vertical sectional view of a centrifugal machine illustrating my invention; Fig. 2, is a perspective view of the end of the driving shaft; and Fig. 3, is an enlarged section illustrating the coupling between the driving shaft and the basket shaft of the machine.

A is the base of the machine.

B is a casing mounted upon the base and provided with a cover 6.

A is a bearing extending partly into the casing B and into the base A. In this hearing is mounted a vertical shaft E carrying at its upper end the basket D. The hub (Z of the basket is preferably made in the manner shown in Fig. 1, having a perforated wall 03.

d is a screen suitably mounted at the pe riphery of the basket.

F is a turbine engine casing mounted in the lower portion of the base A and this casing has a bearing f for a vertical driving shaft C to which is secured the wheel C of the turbine engine.

The shaft C is suspended from a ball hearing G mounted in the'lower portion of the bearing A, thus dispensing with a step hearing for the shaft O in the casing F; this obviates one of the difficulties in this class of apparatus.

The anti-friction bearing Gr in the present instance consists of two disks 9 g and a series of balls or rollers g mounted in a carriage g situated between the two disks. In the upper disk 9 is a seat 9 for the enlarged end 0 of the shaft C, forming in fact a ball and socket joint. The shaft is suspended from this disk and is held laterally by the bearing f as well as by a bearing in the cap a which retains the ball bearing in place.

The upper end of the shaft C is rounded as at 0 and the end of the shaft E is concaved to fit the rounded end of the shaft C and also has a transverse slot 6 into which extends the key 6, which is secured in a slot in the head of the shaft C, preferably by a transverse pin 6 Thus the shaft E rests upon the head of the shaft C, which in turn is carried by the ball bearing G, and the shaft E is driven by the shaft C through the key e. The shaft E is perfectly free with the exception that it must rotate with the shaft C and it can be readily removed with the basket, if desired, without disturbing the driving shaft C.

I claim 1. The combination of a driving shaft having an enlarged and rounded head, a ball bearing consisting of upper and lower plates and intervening balls, a socket in the upper plate adapted to receive the enlarged and rounded head of the said driving shaft, a driven shaft mounted above the said driving shaft and concaved at its lower end to fit over the rounded head of the driving shaft, a key secured to the driving shaft, the driven shaft having a slot in which the key extends, and means for turning the driving shaft.

2. The combination of a tubular supporting structure; two plates within said struc ture having anti-friction elements between them; a downwardly extending shaft section supported on and extending through said two plates; a shaft supported on and extending upwardly from said shaft section; with driving means connected to the downwardly extending shaft section below said bearing plates; there being between the abutting ends of said shaft and shaft section a connection including a rounded head on one of said members and a socket for said head on the other member; with a key positively connecting the head and the socket.

3. The combination of a tubular supporting structure; two plates mounted at the lower end thereof; a shaft terminating adj a- In testimony whereof, I have signed my cent to one of said plates; balls between the 9 name to this specification, in the presence of 10 plates; the lower end of the shaft and one I two subscribing Witnesses.

of the lates bein rovided with rounded recesses a shaft sgctiion projecting through THOMAS PATTERSOI\' the plates and having a head fitting said re- WVitnesses:

cesses; with means for operatively coupling WM. E. SHUPE,

said shaft and the shaft section. WM. A. BARR.
